727 in a early A?

Yeah my tunnel was so tight it used to rub on the trans case on the passenger side . I had to take a large block of wood, big hammer and more or less raise the floor a little from the bottom side while being carefull not to dent or bend crease etc the floor. I also decided this last go around to make an access panel on the drivers side to allow me to adjust the band, change or tighter, pressure test line fittings, trans the shioft cable a lot easier. The panel is not et finished, I just have the opening. But I want a panel I can remove after the carpet is pulled back. So I am going to work on this some and reform the tunnel a little larger. I think you will see no real diff. once the carpet is in place.

It is just so hard to get to the lines, cable on the shifter etc on this car. And add to that the TTI headers collectors are right there too.

I will get some pics soon for you to see,

What engine are you running in the Dart of yours?

Rear end gears etc?
